INNOVATION IN MOTION

The DLS series of draw-wire linear industrial position sensors are a cost effective way tomeasure linear displacements up to 5000mm in the most demanding industrial environments. Using proven potentiometer and encoder technologies to provide analog or digital signals proportional to the displacement of a retractable steel wire, these sensors are ideally suited to a diverse range of applications where only minimal space is available. Applications include fork lifts, elevators, cranes, irrigation gates, automotive crash testing and airframe structural testing.

The operating principle

Draw-wire linear position sensors measure the linear movement of a component via a highly flexible steel wire which is wound onto a drum by a durable spring-driven motor. The winding drum is linked axially to a multi-turn potentiometer, incremental encoder or absolute encoder. A linear movement is transformed into a rotation by the draw-wire principle and converted into a proportional analog signal or to countable increments. Versions with integral electronics produce voltage and current signals at the output which are proportional to the displacement. Draw-wire sensors are simple in application and represent a very economical investment. There is a significant advantage in that, despite their compact installation size, the sensors can cover large measurement ranges.
